Guest blogger and 2014 Ontario Bioblitz Bird Taxon team leader Kevin Kerr, Curator of Birds at Toronto Zoo, writes on some of his experiences inventorying birds, including 9 species-at-risk, from the Humber River Watershed.

The 2014 Ontario BioBlitz brought 500+ registrants together this past weekend to find and catalogue biodiversity in the Humber River watershed, and students from the Environmental Visual Communication (EVC) Program were there to capture the event from every angle.
